Detection of deception on the Millon Clinical Multiaxial Inventory (MCMI).
Subjects from a correctional inmate (94 incarcerated males with no history of psychiatric treatment) and a forensic inpatient (144 males and 7 females) setting were divided into distorted and nondistorted groups based on "fake bad" instructions and concurrent MMPI profiles. All subjects also were administered the MCMI. Significant differences were found between groups for MCMI profile validity, weight factor scores, and total profile correction scores. MCMI profiles were consistent with expected symptomatology, test design, and previous research. Results suggest that MCMI weight factor scores may be valuable indicators of symptom distortion in otherwise valid profiles in forensic settings. Results also indicated that the diagnostic accuracy of MCMI reports may vary greatly in relation to clinical population, symptom prevalence, and diagnostic category.
